Lanthanide Complexes Formed with the Tri- and Tetraacetate Derivatives of Bis(aminomethyl)phosphinic Acid: Equilibrium, Kinetic and NMR Spectroscopic Studies

André Merbach, Eva Jakab Toth, Laurent Quebatte

The lanthanide(III) complexes formed with the tri- and tetraacetate derivatives of bis(aminomethyl)phosphinic acid, L1 and L2, respectively, have been studied by pH potentiometry, spectrophotometry and 1H and 17O NMR spectroscopy. L1 forms [Ln(L1)], [Ln(L1 ...

Synthesis, Structure and Reactivity of Homo- and Heterobimetallic Complexes of the General Formula [CpRu(m-Cl)3ML] (LM = (arene)Ru, CpRh, Cp*Ir)

Rosario Scopelliti, Kay Severin, Laurent Quebatte

The homo- and heterobimetallic complexes [CpRu(m-Cl)3-ML] [LM = (C6H6)Ru, (cymene)Ru, (1,3,5-C6H3iPr3)Ru, CpRh, CpIr] were prepd. by reaction of [CpRu(m-OMe)]2 with Me3SiCl and subsequent addn. of [LMCl2]2. The complexes [Cp*Ru(m-Cl)3Ru(cymene)] and [C ...

New polynuclear catalysts for atom-transfer radical addition reactions

Laurent Quebatte

Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...

A bimetallic ruthenium ethylene complex as a catalyst precursor for the Kharasch reaction

Kay Severin, Euro Solari, Laurent Quebatte

A bimetallic complex, in which a RuCl2 (eta(2)C(2)H(4))(PCy3) fragment is connected via three chloro, bridges to a (eta(6)-p-cymene)RuCl2 fragment, has been synthesized and characterized by single-crystal X-ray crystallography. This complex was used to cat ...

Atom transfer radical additions with the cationic half-sandwich complex [Cp*Ru(PPh3)(2)(CH3CN)]OTf

Rosario Scopelliti, Kay Severin, Laurent Quebatte

The cationic ruthenium half-sandwich complex [CpRu(PPh3)(2)(CH3CN)][OTf] (2) (CP = eta(5)-C5Me5, OTf = SO3CF3) was synthesized by reduction of Cp*RuCl2 with zinc in the presence of NaOTf and subsequent reaction with PPh3. When NaOTf was omitted, the ...
